fix(web): map claim status 1 to 已认领 instead of showing the raw digit (#337)

The frontend's claimStatusMeta only mapped English pseudo-values
(pending/claimed/rejected) that never existed in yeeke's real data — the
API's confirmed status is the raw string "1" (HAR, #336 requirement
doc). Every known-status row fell through to the unstyled default and
showed a bare "1". The claimStatus filter had the same mismatch: its
options never equaled the backend's claim_status = <raw value> filter,
so filtering by 已认领/待认领/已拒绝 silently returned nothing.

Map "1" to 已认领 and drop the two never-observed pseudo-statuses from
the filter, per the project rule that unmapped values must stay visible
and flagged rather than guessed at.

+     * bottom bar — on the Samsung sample the bottom bar is a label-less 31px FrameLayout
+     * whose only text node is zero-size, so a naive scan falls through to the next
+     * lowest labelled leaf, which sits in the PAYMENT-METHOD row above it, and the climb
+     * from there lands the click on "change payment method" instead of the order button.
+     *
+     * Step 1 — row: among visible/enabled/non-zero-size CLICKABLE nodes inside the
+     * recognized panel's container (#331 judgment) with height ≤ [SUBMIT_ROW_MAX_HEIGHT_PERCENT]
+     * of screen height (same guard as 2bc624f, keeps a full-sheet/full-body wrapper from
+     * ever being "the row"), pick the one with the lowest bottom edge; ties go to the
+     * rightmost. This row — and only this row — may hold the order button. If its own
+     * subtree matches a payment-method alias (`textAliases.specPanel.paymentAreaAliases`,
+     * e.g. 微信支付/先用后付/支付方式) or [SUBMIT_TARGET_BLOCKED_MARKERS], fail explicitly;
+     * never fall back to a higher row — a higher row is never the order button either.
+     *
+     * Step 2 — leaf: within that row's own subtree (or the row itself), among
+     * visible/non-zero-size nodes with a NON-BLANK OWN LABEL whose nearest clickable
+     * ancestor is EXACTLY that row (not some nested sub-button, and not a higher row),
+     * pick the bottom-right-most one. [PurchaseUiDriver.clickFresh] re-finds its target

+     * and only then climbs to the nearest clickable ancestor and clicks it (see

+     * [SnapshotNode.label] is `""` but its live `preferredOrDescendantLabel()` digs into a
+     * child, so the re-find would always miss (task 594: TARGET_NOT_FOUND right after the
+     * irreversible boundary). Aiming at the labelled leaf — the same convention already
+     * used by `ImageSearchCandidatePolicy.clickTargetInside` — lets clickFresh's own
+     * climb-to-ancestor logic land the tap back on the row. If the row has no such leaf
